Air conditioner price is based on several factors: brand, energy efficiency, and size range. These all need to be taken into account before you buy your new air conditioner.
Energy Guide Label
Energy guide labels can be found on most air conditioners. They compare the operating costs, size range, and energy cost of different air conditioners. As it compares the energy cost of conditioners that are the same size, it is important that you know how much air you will need to circulate through your home. Will you be cooling one room, or will you purchase a central air conditioner? Depending on the size of your home, it may be cheaper to buy several single room units than a central one. However, it can be more convenient to buy a single unit that can be controlled from one place.
Seasonal Energy Efficiency Ratio
The seasonal energy efficiency ratio (SEER) is the efficiency ratio used for central air conditioners. The higher the ratio, the less energy it uses. These machines have a higher purchase price than machines with a lower ratio. However, your electricity bill will be much lower than if you buy a less efficient machine. This will save you money in the long run.
Energy Efficiency Ratio
The energy efficiency ratio (EER) is used to indicate the efficiency ratio for single room air conditioners. This ratio works just like the (SEER), the different name allows you to differentiate between the two when you are considering your purchase.
Sensible Heat Factor
The sensible heat factor (SHF) indicates how much moisture is removed from the air. The lower the number, the more moisture is removed. The scale ranges from 0.5 to 1.0. If you live in a place with high humidity, you will want a range between 0.67 and 0.77. However, it will often be cheaper to buy a separate dehumidifier. The SHF depends on the blower speed and coil type. These are often quite expensive when compared to the blower and coil of an air conditioner with a higher SHF.
Each brand of air conditioner has its own claims to its use and effectiveness. It is a good idea to thoroughly research each brand you are considering. You also need to decide if you want your whole house cooled or only parts of it. The cost of running an air conditioner depends on the area it needs to cool, the outside temperature and the efficiency of the unit. Before you decide on central air, consider opening your windows at night and letting your home cool naturally. This will not work as well in extreme climates, but for those who live in a temperate zone, it could save more money and energy in the end. Wherever you live, closing the curtains and window during the day will help prevent the cool air from escaping, which means less work for the conditioner.
